How long after we cap a landfill can we build on it?

    It appears that there is not sufficient research to answer this question in much detail. It is certainly possible to revegetate a closed landfill with native grasses and plants, although precautions need to be taken to ensure the long-term stability of the site. For example, it is ill-advised to introduce deep-rooted plants to a closed site as it may facilitate water infiltration but trees are acceptable provided they are carefully placed.

    As for placing buildings on a capped landfill, it is not advisable without “extensive site engineering.” Additionally, landfills may even produce gases over 30 years after their closure, which can pose health risks to those exposed. However, turning the sites into wildlife habitats or golf courses seems to be feasible.
